Carbon concentration in the world's trees across climatic gradients

What is it about?

Carbon (C) concentrations are an important chemical characteristic of wood, but our understanding of why tree species express different wood C concentrations is lacking. We find that environmental variables including temperature, precipitation, and seasonality determine wood C concentrations in trees. We also find evidence that increasing temperatures, as are expected under climate change, are likely to decrease wood C concentrations in the future.
